I think you should give her some shoulder pads in the final dress. And pin the CB seam down a bit further to about the waist line.

What sort of fabric are you going to use for the dress?

"Nur der ist Meister seiner Kunst, der immer sucht, das Gute zu verbessern und niemals glaubt, das Beste schon zu haben.""Only he is a master of his art who always seeks to improve the good and never believes to have the best already"

I have three dresses to do
a. loose cotton with belt shirt dress - acorn shirting striped
b. very thin cotton like chiffon see trough with some side folds gathered at the waist, chocolate brown with white coffe polka dots
c. thin wool simple dress from cool breeze holland and sherry burgundy rusty red, probablj princess seam all the way down panels and raglan sleeves
